Beitknown that LTHEODOR KUNDTZ,a resi# dent of Cleveland, countyefCuyahoga, `and State of Ohio, have invented certain new and usefulImprovements in Cabinets for Sewng-r Machines, dac.; and I do herebydeclare the following to be a full, clear, and exact descripf tion ofthe invention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to improvements in cabinets for sewing-machines,dac., comprising a load-carrying leaf that carries the machine oraportion of the latter and is tiltable vertically below the top of thecabinet and a lifting leaf hinged to the cabinet-top and operativelyconnected with the loadfcarrying eaf.

The object of my present invention is to provide an improved and simpleand durable operative connection between the lifting leaf and theload-carrying leaf.

lVith this object in view and to the end of realizing other resultshereinafter referred t-o my invention consists in certain featuresofconstruction and combinations of parts here-V inafter described, andpoint-ed out in the claims.

In the accompanying drawings, Figure I is a top plan of a cabinetembodying my invention. Fig. II is a longitudinal'vertical section of aportion of the cabinet on line IIII, Fig. I, looking -rearwardly. Fig.III is a transverse vertical section of the cabinet on line'III III,Fig. I, looking leftward. Fig. IV is a transverse vertical section of aportion of the cabinet'and corresponds with Fig. III, except that inFig. IV the load-carrying leaf is shown in its downwardly-tiltedposition and the lifting leaf is closed down over the opening in the topof the cabinet. Fig. V is a transverse vertical section correspondingwith Fig. IV, except that in Fig. V the loadcarrying leaf and thelifting leaf are shown in an intermediate position. Fig. VI is a frontside elevation, mostly in section, online VI VI, Fig. V. Fig. VII is aview in perspective ofthe leaf 7c.

' Referring to the drawings, a designates the top of the cabinet; b, thecabinets back; c, the left-hand end wall of cabinet, and d a doorforming the forward side of the cabinet and hinged to the wall c at d'.A vertical quadrangular opening ci is formed in centrallyof and extendsthrough the top a.

c designates the vertically-tilting load-carrying leaf that, when thecabinet is fitted up as a sewing-machine cabinet, bearsthesewing-machine head. (Not shown.) Leaf e in its elevated orupwardly-tilted position closes the central and rear portions of openinga. Leaf e at or near its rear edge is pivoted horizontally andlongitudinally of the cabinet, as at e', to the top ct. l Leaf eisoperatively connected with the lifting leaf f, that is hingedhorizontally and transversely of the cabinet, as at f', to the left-handend of the cabinettop, and the axial line of the leaf f is arranged atright angles to the axial line of the leafe. The arrangement of parts issuch that when leaf e occupies the opening a leaf shown in Figs. I, II,and III, and when the said leaf f is tilted to the right over theopening a leaf e isin its downwardly-tilted position, as shown in Fig.IV. The operative connection between the leaf upper end of thewall c ofthe cabinet and has its free end odset as required, as at g2, to renderthe said end capable of extending in under and bearing the load-carryingleaf e. lThe lever g extends `not only-innnder the leaf e,` butlongitudinally of the axial 4line of the said leaf. The upper end of theWall c forms a fulcrum c for the lever g, as shown very clearly inFig..VI,`and` the leaf f and the top a are recessed and cut away at h,as required to accommodate the 'location and operation of the saidlever.` It Will be observed that the said lever is located, preferably,about centrally between the forward side and rear side of the cabinet,so as to render it capable of extending under the forward leaves f and@,extends from leaf f over the v f forms a leftward extension of the topd, as l j and the leaf e forms an important feature IOO portion of theleaf e. The offset 'portion-or. free end o f the lever g is providedwith a rearwardly-extendin g curved arm g3, that extends under theleft-hand portion of the leaf e and as shown in Fig. IV, that the saidroller rides c forwardly upon the said arm during'- the 'ele vation ofthe said arm from thejlatters low-f." ermost position, that lcheelevation of the said arm accompanies the actuation of jthe leaf f fromthe latters opening-*closing position, that, whenthze leaf e has beenlifted about half-way the odset portion or free end of the hand end, asshown in Figs. V and VI, and that the said portion or end of the leverbears the said leaf in the. latters upwardly-,tilted and openingfclosingposition, as shown in Fig, II. The lever g and its arm g3 are made,preferably, inone piece, and the construction is obviof'ufsly simple,durable, and convenient.

The wall c is preferably provided upon its inner side with a guide-platei', that is se. cured to the said wall .in any approved man? ner vandhas alvertically-arranged channel 17, arranged to` be engaged by andguide or steady the free end ofthe lever g, as shown in Figs. IV and VI,during the lifting of the The sewing-.machine head orother machine {no tshown) that is mounted upon and se,

,. cured to the leaf e requires the; extension of l cabinet, as at le',to the forward portion .of

the topa and has its rear edge provided with a tongue k2, that extendslongitudinally of the leaf lo and is overlapped in the elevated positionof the leaves c and 7s by a tongue e2, formed upon the forward edge ofthe leaf e, When the leaf c is tilted downwardly, the leaf le tiltsdownwardly by gravity, anda forwardly-,projecting arm e4 of the leaf eis ar-` rangedto .extend in under and engage and liftjthe leaf k whenthe leaf e is tilted up-y wardly from the latters lower position. The

said .leaf is cut away at its tongue, as at 154, to, accommodate thelocation and operation of dere?? arranged to engage, the underside ofthe tongue of the said leaf in the upwardly tilted position of theleaves e and 7c, as shown in-Fig. III. Lever g, through the medium ofits arm g3 and the roller of the leaf e, supports the latter and itsload in the upwardlytilted position of the said leaf, and theforwardly-projecting arnrof the lleaf e is not only instrumental intilting the leaf k up- 1 inwardly, bntaffords bearingfor the said leafin `the latters upwardly-tilted position. The top a is cutawayalsouponits under side, as at a?, to accommodate the location of theroller e3V -in the upwardly-tilted position of the leaf e.

What I claim is-r l 1. In a cabinet of the character indicated, thecombi'natiomwith a cabinet-top having an opening therethrough, thevertically-tilt- 1 ing load-carrying leaf e provided with a roller e3,and hinged. orpivoted at or near its 1 rear edge,horizontallyand-longitudinally of d l the cabinet, to the aforesaid topAand arranged lever gfbears the said leaf e at the latters left-fl tooccupy the aforesaid opening in'its'npl wardly-tilted position, yand thelifting leaf l hinged, horizontally and transverselyof the cabinet, toone end of the cabinet-.top and at right angles to the axial line oftheload-carrying leaf, of a lever pivoted at one end, to andtransversely of thelifting leaf centrally between the rear and forwardedges of the said leaf, which lever extends in under the load-.carryingvleaf between the. rearand forward edges of the load-carrying leaf, andis provided, below the load-.carrying leaf, with a rearwardly-extendingarm, and the said lever and its aforesaid rearwardly-extending armhaving such yarrangement vand trend, relative to the aforesaid roller,that the lever-arm shall engage the roller from below and beinstrumental in liftingV the load-.carrying leafpart of the way from thelatters lower position, and thereupon the lever shall directly engagethesaidleaf from below and complete the lifting operation.

2. AThe combination of the cabinetrtop provided with an opening a; avertically-,tiltable loadcarrying leaf e having its left-hand endprovided with a roller es,y which leaf is hinged to the top, at the rearof the said opening, horizontally7 and longitudinally of the cabinet;thelifting leaf hinged, `horizontally and/longitudinally of thecabiet,to the left-.handend of thetop; the leverg pivoted to andhorizontallyand transverselyAOf the lifting leaf betweenrthe rear andforward edges of the said leaf, and extending to and `Offset, as at 912,in under the load-carrying leaf and having its .offset portion providedi with a rearwardly-.extending arm g3, and the left-hand end portion ofthe cabinet forming a fulcrum or bearing for/ the said lever, allarranged and operating substantially as i Y l shown, for the purposespecified.

leaf is shown detached in Fig.Y VII, and the 1 3.- In a cabinet of thecharacter indicated,
